Orlando written test books

Good evening brothers and sisters,

Does anybody know which Fire book and EMS book should be used to study for the Orlando written test? From what I've gathered through searching the forums, it used to be a Brady EMT book and an IFSTA book. Unfortunately there are two sixth edition IFSTA books released this year, one of which includes EMS and HAZMAT, and two EMT-B books by Brady, each written by a different author.
